This research aims to study the effect of inquiry learning by critical thinking practice followed by a conceptual change efforts to reduce misconceptions on acid-base learn. The research design using one-group pretest-posttest design with students of SMAN 2 Ngawi as sample research. The student conception status finding by knowing concept (TK), not knowing concept (TTK), and misconception (MK), whereas intensity of misconception be analized by CRI. Results and analysis of research data found that there is a shift in conception after inquiry learning p rocess. Based on Wilcoxon’s signed rank test, the T value of test TK, TTK, and MK is less than T table at α = 0.05 , so it was concluded that inquiry learning increase TK and decrease TTK and MK. The influence of inquiry learning for understanding the influence was strengthened by the results of the t test tests before and after understanding the concept of inquiry learning that indicate a significant difference. t-test results on tests of critical thinking before and after the inquiry learning also showed a significant difference. Inquiry learning can not reduce all of misconceptions. Reduction step again is with conceptual change. Based on Wilcoxon’s signed rank test was concluded that conceptual change learning can reduce misconception significantlyPenelitian ini bertujuan mempelajari pengaruh pembelajaran inkuiri terbuka disertai latihan berpikir kritis yang dilanjutkan dengan conceptual change sebagai upaya mereduksi miskonsepsi pada materi asam basa. Penelitian eksperimen semu ini menggunakan metode one group pretest-postest design dengan subyek penelitian siswa kelas XI SMA Negeri 2 Ngawi. Profil konsepsi siswa dinyatakan dengan status tahu konsep (TK), tidak tahu konsep (TTK), dan miskonsepsi (MK), sedangkan intensitas miskonsepsi diperoleh dari hasil analisis CRI jawaban siswa. Hasil dan analisis hasil tes pemahaman konsep menemukan bahwa terjadi pergeseran konsepsi setelah proses pembelajaran inkuiri terbuka. Berdasarkan wilcoxon’s signed rank test diperoleh T hitung untuk semua status TK, TTK, dan MK kurang dari nilai T tabel pada α = 0,05 dan n = 25, sehingga disimpulkan bahwa pembelajaran inkuiri meningkatkan jumlah TK dan menurunkan TTK dan MK. Pengaruh pembelajaran inkuiri terhadap pemahaman konsep serta kemampuan berpikir kritis diketahui dari uji t hasil tes pemahaman konsep serta tes berpikir kritis sebelum dan setelah pembelajaran. Hasil uji t pada α = 0,05 menunjukkan adanya perbedaan signifikan pemahaman konsep serta kemampuan berpikir kritis antara sebelum dan setelah pembelajaran inkuiri. Miskonsepsi yang masih tersisa setelah pembelajaran inkuiri direduksi kembali dengan strategi conceptual change. Berdasarkan wilcoxon’s signed rangk test disimpulkan bahwa pembelajaran conceptual change dapat mereduksi miskonsepsi secara signifikan.

ABSTRACT: Modification of threshold exemption from import duties was tested whether changing consumer preferences in shopping from abroad. This study uses a paired test with the initial hypothesis that there is no difference in the daily average value of imports before and after the policy is applied. The research data is only from the Customs offices which have services for shipment items (32 offices) on October 1, 2019, to March 2, 2020. Descriptive statistical results show that the average was USD135,065, then dropped to USD127,430. Based on the results, both the Paired Sample T Test and The Wilcoxon Signed Rank Test obtained a p-value of 0,000, meaning that the initial hypothesis was rejected. The adoption of this policy has changed the preferences of consumers shopping from abroad. The Government's aim to reduce the trade balance deficit and protect domestic businesses appears to be successful, however, if there are no substitute goods available in the country, the import will only move from importing consignment goods to general imports. The novelty is the variable of import duty on shopping preferences is not widely used. The limitation of this study only measures changes in spending preferences, do not in state revenue.Keywords: shopping preference, consignment, tax exemption, difference test ABSTRAK:Perubahan kebijakan batas pembebasan terhadap bea masuk dan pajak atas impor barang kiriman diuji apakah merubah preferensi konsumen dalam berbelanja barang yang dikirim langsung dari luar negeri melalui mekanisme impor barang kiriman. Penelitian ini menggunakan metode kuantitatif melalui uji berpasangan dengan hipotesis awal tidak adanya perbedaan nilai rerata impor harian baik sebelum maupun setelah kebijakan berlaku. Data penelitian hanya kantor-kantor Bea Cukai yang memiliki pelayanan atas barang kiriman (32 kantor) pada 1 Oktober 2019 sampai dengan 2 Maret 2020. Hasil statistik deskriptif menunjukkan bahwa rerata harian impor sebelum kebijakan tersebut berlaku sebesar USD135.065, kemudian turun menjadi USD127.430. Berdasarkan pengujian, baik pada Paired Sampel T Test maupun pada Wilcoxon Signed Rank Test diperoleh nilai p sebesar 0.000 (hipotesis awal ditolak). Hal ini berarti penerapan kebijakan tersebut telah merubah preferensi belanja dari luar negeri melalui impor barang kiriman. Tujuan Pemerintah untuk mengurangi defisit neraca perdagangan dan melindungi usaha dalam negeri tampaknya berhasil, namun apabila belum tersedia barang subtitusi di dalam negeri, importasi tersebut hanya akan berpindah dari impor barang kiriman menjadi impor umum. Keterbaruan pada penelitian ini adalah variabel bea masuk pada preferensi belanja belum banyak digunakan. Keterbatasan penelitian ini hanya mengukur perubahan preferensi belanja, tidak mengukur perubahan penerimaan negara.Kata Kunci: preferensi belanja, impor barang kiriman, pembebasan pajak, uji beda

OBJECTIVE: To compare broth microdilution and E-test minimum inhibitory concentrations (MICs) of 4 fluoroquinolones against Streptococcus pneumoniae and to determine the effect of these in vitro MIC methods on the calculation of AUC0–24/MIC ratios. METHODS: Levofloxacin, gatifloxacin, moxifloxacin, and gemifloxacin MICs were determined by broth microdilution (incubated in air) and E-test (incubated in CO2) for 100 clinical isolates of S. pneumoniae. MIC50, MIC90, and geometric mean MIC were calculated. Steady-state serum concentration—time profiles were simulated for once-daily, oral dosing of levofloxacin 500 mg, gatifloxacin 400 mg, moxifloxacin 400 mg, and gemifloxacin 320 mg. After correcting for protein binding, AUC0–24 of unbound drug was calculated for each regimen, and AUC0–24/MIC ratios were calculated using MIC data from both in vitro methods. Differences in MICs between methods were determined for each agent using the paired t-test (after logarithmic transformation of MICs) and the Wilcoxon signed-rank test. Differences in AUC0–24/MIC ratios were also determined using the paired t-test and the Wilcoxon signed-rank test. The level of significance for all analyses was p < 0.05. RESULTS: Broth microdilution and E-test MICs were within ± 1 log2 dilution for 94%, 93%, 61%, and 35% of the isolates for levofloxacin, gatifloxacin, moxifloxacin, and gemifloxacin, respectively. Broth microdilution MICs were significantly lower than E-test MICs for all 4 agents (p < 0.001). However, a categorical change in susceptibility was seen for only 1 isolate with gatifloxacin and moxifloxacin (intermediate by broth microdilution, resistant by E-test). AUC0–24/MIC ratios were significantly higher for each regimen when MICs were determined by broth microdilution compared with E-test (p < 0.001). CONCLUSIONS: There is a significant difference in the activity of the newer fluoroquinolones against S. pneumoniae when MICs are determined by broth microdilution and E-test. When evaluating fluoroquinolone activity and pharmacodynamics against this organism, clinicians must be aware that MIC testing methodology may have a significant impact on the results.

Many things can be done to reduce stress, one of them is through Graffiti and Mural. Both are recognized to reduce stress levels in a person. The purpose of this study is to find out how to reduce stress levels and differences in stress levels before and after treatment in the form of drawing graffiti and murals in the Purbalingga Street Art (PUSAR) community. This type of research is a quantitative quasi experiment. To measure stress levels, the instrument used is the Depression Anxiety Stress Scale (DASS). The stress difference was analyzed using the Wilcoxon signed rank test. The results of the study stated that graffiti and murals can cause a sense of fun and calm when the artist holds a pilox (spray paint) on the object of the wall. Then, there is a point in making graffiti that makes a graffiti artist feel satisfied to express and express emotions from within himself. So that what makes graffiti and murals can overcome problems and cause pleasure is when all emotions can be overflowed into his work. Furthermore, every member of the Purbalingga Street Art (PUSAR) community with different stress levels get different results. Statistical test results show a significant difference or decrease in stress levels in the study subjects with the results of p value = 0.011 (p value <0.05), so the hypothesis is accepted. Banyak hal yang dapat dilakukan untuk mereduksi stress, salah satunya melalui Graffiti dan Mural. Keduanya diakui dapat mengurangi tingkat stress pada seseorang. Tujuan dari penelitian ini adalah mengetahui cara mereduksi tingkat stress dan perbedaan tingkat stress sebelum dan sesudah dilakukannya perlakuan berupa menggambar graffiti dan mural pada komunitas Purbalingga Street Art (PUSAR). Jenis penelitian ini adalah kuantitatif quasi eksperimen. Untuk mengukur tingkat stress, instrumen yang digunakan adalah skala Depression Anxiety Stress Scale (DASS). Perbedaan stress tersebut dianalisis menggunakan uji wilcoxon signed rank. Hasil penelitian menyatakan bahwa graffiti dan mural dapat menimbulkan rasa senang serta ketenangan ketika artist memegang pilox (cat semprot) pada obyek tembok. Kemudian, ada sebuah titik dalam pembuatan graffiti yang membuat seorang artist graffiti merasa puas untuk mengungkapkan dan mengekspresikan emosi dari dalam dirinya. Sehingga yang membuat graffiti dan mural dapat mengatasi masalah dan menimbulkan rasa senang adalah saat semua emosi dapat diluapkan ke karyanya. Selanjutnya, setiap anggotakomunitas Purbalingga Street Art (PUSAR) dengan tingkat stress yang berbeda mendapatkan hasil yang berbeda pula. Hasil uji statistik menunjukan perbedaan atau penurunan tingkat stress yang signifikan pada subjek penelitian dengan hasil p value = 0,011 (p value < 0,05), sehingga hipotesis diterima.

Background: Infant tongue-tie can cause breastfeeding problems, which may be improved by frenotomy. However, controversy exists among the medical community. Research aim: To examine the influence of frenotomy on infants with posterior ankyloglossia, by quantifying the changes in breastfeeding and maternal nipple pain using standardized tools. Methods: Newborns ( N = 30) below 12 weeks of age were recruited from the Herzl–Goldfarb Breastfeeding Clinic between April 2014 and April 2015. Diagnosis of posterior ankyloglossia was made clinically. Frenotomy was performed. Mothers received breastfeeding counseling before and after the procedure. Pain and breastfeeding were assessed before the procedure, immediately after the procedure, and after 2 days, 7 days and 14 days. Breastfeeding was assessed using the LATCH Tool and by subjective questioning. Maternal nipple pain was assessed using the Numeric Rating System. Results: No complications were reported with frenotomy. There was a significant improvement in LATCH score immediately post-frenotomy, with an increase in median scores from 7.5 to 8.5 ( p < .0001, Wilcoxon signed rank test). There was a significant decrease in median pain score immediately post-frenotomy, from 3.0 on the left nipple and 3.25 on the right nipple, to 0 bilaterally ( p < .0001, Wilcoxon signed rank test). Subjective improvement in breastfeeding was reported by 90% of mothers immediately after frenotomy and 83% of mothers at Day 14. Conclusion: Frenotomy for posterior ankyloglossia may improve breastfeeding and nipple pain.
